Stainless hlau welded kav yuav muaj ntau yam teeb meem thaum lub vuam cov txheej txheem, xws li undercuts, paces, tsis muaj cai, tsis meej, thiab lwm yam. Tom qab ntawd, dab tsi tawg koj paub thaum vuam stainless hlau welded kav?
1. Kub tawg
Nws yog hais txog vuam crack generated los ntawm cov hlau nyob rau hauv weld thiab cua sov tuaj cheeb tsam thaum lub ntsuas kub nyob ze ntawm cov kab ke. Kev tiv thaiv kev ntsuas: nruj me ntsis tswj cov ntsiab lus ntawm cov kev phom sij xws li leej faj thiab phosphorus nyob rau hauv stainless hlau welded cov khoom siv welded, txo cov rhiab ntawm cov kab nrib pleb kub; Kho cov tshuaj lom neeg cov tshuaj lom neeg ntawm weld hlau, txhim kho weld microstructure, refine nplej, thiab txhim kho lub ntsej muag zoo. Txo lossis tawg cov qib cais; Siv cov khoom siv vuam kom txo cov ntsiab lus ntawm impurities nyob rau hauv weld thiab txhim kho cov degregation.
2. Txias tawg
Nws yog hais txog qhov tawg nrawm rau thaum welded sib koom ua ke yog txias rau qhov kub tsawg dua, uas yog hu ua txias tawg. Kev Tiv Thaiv Tiv Thaiv: Siv cov khoom siv roj qis hom vuam, nruj me ntsis ua raws cov lus qhia ua ntej siv; Tshem tawm cov roj thiab noo noo ntawm cov weldments ua ntej vuam, txo cov ntsiab lus hydrogen hauv Weld; Xaiv cov txheej txheem vuam tsim nyog thiab cov lus qhia tshav kub kom txo qis kev kho hydrogen sai sai tom qab siv hydrogen kom dim ntawm welded sib koom tes;
3. Rheat tawg
Nws yog hais txog cov nrib pleb tom qab stainless hlau welded yeeb nkab kho kom zoo dua (kev nyuaj siab-txheej txheem kev kub ntxhov), uas yog hu ua Reheat tawg.
Kev tiv thaiv kev ntsuas: hauv ntej ntawm kev sib ntsib cov qauv tsim qauv, kom cov weld-zog vuam siv, kom cov weld-zog nyob rau hauv weld, zam cov kab nrib pleb; txo cov vuam kev sib cav sib ceg thiab kev ntxhov siab; Tswj lub vuam tshav kub tawm tswv yim ntawm cov yeeb nkab welded, tsim nyog xaiv cov preheating thiab kub kho kub thiab kub kho kom ntau li ntau tau.
Stainless hlau welded yeeb nkab yuav tsum them sai sai rau ib puag ncig ib puag ncig thaum lub sij hawm tsim khoom, thiab ua kom haum thiab ua cov ntaub ntawv. Hauv kev sib xyaw nrog cov kev mob uas cuam tshuam los ntawm cov tuam ntxhab ntawm cov hlau stainless welded kav, Hangao Tech (Seko Machinery)s Kev ceev stainless hlau welded yeeb nkab rajting ua tshuab siv seuromagetic system tswj hwm kev ua haujlwm zoo rau hluav taws xob, uas tau txhim kho cov efficiency thiab zoo ntawm vuam. Nyob rau tib lub sijhawm, eddy tsis muaj tus ntes yog siv ua ke los saib xyuas sab hauv phab ntsa ntawm welded yeeb nkab txhua lub sijhawm. Tus ntse plc system cov neeg saib xyuas thiab sau cov ntaub ntawv ntau lawm ntawm cov yeeb nkab welded hauv lub sijhawm tiag tiag, yog li ntawd cov txiaj ntsig tau zoo heev, yog li txo tus nqi.
